The producer got struck down with a disease while recording the US garage rock group after they decided to eat raw liver in the studio to prepare for recording their track 'Raw Meat'.
Band member Cole Alexander explained: "To get in the mood to record 'Raw Meat' we started eating all this liver sashimi. Then we all started getting sick from it. Mark had to go to hospital because his fever was so high. His brain was cooking, man."
Mark said the experience left him "moaning and groaning," but despite the fact his health was at risk he doesn't hold it against the group.
He told NME magazine: "I thought maybe I was hungover or something. Then I started shivering uncontrollably. The next thing, the band are putting all these blankets over me. I wake up an hour later , just f***ing moaning and groaning.
"One of them touched my skin and they were like 'Listen dude, we've got to get you to a hospital.'
"When I was there I was diagnosed with something with a lot of syllables in it - endorhinitis, or something like that. I almost died. But I don't think it was intentional on their part."
